The policy is that once UTXOs have been spent, we cannot reverse those transactions in the blockchain itself due to its immutable nature. When I mentioned reversing UTXOs that went through mixers, it was about tracking and potentially recovering those funds, not reversing the transaction in the traditional sense. The focus is on tracing where the funds have gone and working with exchanges or wallets to recover them, rather than altering the blockchain record.
well you can say that NOW but that's not what you said in the previous posting. Take a look:
3. Dealing with Mixed Transactions: Bitcoin mixers complicate the traceability of funds. In situations where mixed or shuffled funds are involved, the CVNs (Community Verification Nodes) would employ advanced forensic tools that analyze transaction patterns and mixer outputs. However, reversing transactions involving mixed funds would be approached with extreme caution to avoid affecting innocent users. Decisions in such cases would likely require additional layers of verification and possibly a higher threshold of CVN consensus.
you were acting like you MIGHT be willing to reverse transactions that went through mixers anyway but you would just be more careful aka "extreme caution". to me, this type of vagueness cannot be good. because it leads to confusion. you say one thing then you say another. you never clarify completely and then that leads to grey areas.
this whole paragraph doesn't even make any sense either. Since it seems to imply that there is some type of cutoff where if the UTXOs haven't been transferred more than a certain amount of times, you would have the ability and willingness to reverse the transaction. Very unfortunate how vague you are. What does "multiple times" mean? Two times? One time? Maybe you don't even know. But based on what you are saying now, you would only be able to reverse UTXOs that had not been transferred at all. So maybe you need to edit this paragraph.
2. Handling Long Transaction Chains: The Bitcoin Core protocol tracks UTXOs (Unspent Transaction Outputs) efficiently, and this system does not inherently allow for the reversal of entire chains of transactions once UTXOs are spent. In cases where UTXOs have been transferred multiple times, the reversible transaction mechanism would focus only on the most recent transaction where the original UTXOs were still unspent at the time of flagging. This avoids the complication of unraveling long transaction chains.
The system is designed to protect innocent parties by ensuring that any action, such as freezing funds, is only taken when there is high confidence that those funds are directly linked to the theft. The CVNs will carefully review each case to avoid any negative impact on individuals who are not involved in the theft.
The only scenario where I think high confidence exists is if someone can prove they know the private key to the stolen funds. And those funds have not yet been spent. Then you can reverse those UTXOs only. But once the UTXOs have been consumed, that's where you no longer have any confidence at all. So it would be good if you didn't try and reverse anything except the original unspent UTXOs. That's the only thing that I could even partially accept as part of bitcoin.
Any implementation would require broad agreement within the Bitcoin community.
I've lost alot of faith in the community approval process based on things that have happened in bitcoin over the last 2 or so years. I'm not so sure there needs to be broad agreement for something to get shoved into bitcoin anymore.
also, why stop with cases of theft? if you can reverse transactions then you can probably do other things too like help people that lost their bitcoin due to losing their private key get their bitcoin back. all they would need to do is prove the bitcoin belonged to them. people like that guy whose bitcoin is stuck on a hard drive in a landfill. if it's ok to do one of them then it should be ok to do other too right?
